Modern Performance and Handling for your Classic Muscle Car

Let’s face it, cars from the 1960’s just don’t handle that well. Many were legendary straight-line performers, but at the end of the strip drum brakes strained to bring everything to a halt before that looming curve ahead. The ’62-’67 Chevy II Nova became a legend with hot small blocks under its hood and significantly less weight to drag around than full size muscle cars. All the ingredients for greatness were baked in, but the factory suspension left a lot to be desired. With the front spring positioned above the upper control arm and everything bolted up to a stamped sheet metal tub, it’s clear that the GM engineers’ priority was economical production, not extreme performance. 

In the past, many have tried to conquer their Chevy II’s lackluster handling by bolting up individual components. A sway bar here, some better shocks there, and maybe even a disc brake conversion, but these individual upgrades often created new problems or just didn’t quite work as well as expected. It became clear over the years that it would take a completely new approach to really transform the handling personality of a Chevy II Nova.

With the goal of total transformation in mind, Speedway Motors’ engineers went to the drawing board and got to work on a complete bolt-in front suspension designed to infuse these 60’s classics with some modern performance technology. The result is the G-Comp 1962-67 Chevy II Nova Front Suspension Kit.

Optimal Camber and Lowered Ride Height to Keep the Tires Planted

Geometry is at the heart of G-Comp. When Chevy II’s were rolling off the production line, they were equipped with bias-ply tires and mere inches of rubber meeting the road. When pushed hard into a corner, the stock front suspension made matters worse, losing camber as it compressed and leaving the rolled-over tire hanging on for dear life. G-Comp front suspensions are designed to make the most of modern pro-touring tires with wide tread and sticky compounds. G-Comp is engineered with optimal camber gain, meaning that as the suspension compresses in a hard corner, the top of the tire is pulled in, keeping that wide rubber planted to the pavement. 

These cars look great lowered, and the G-Comp suspension will drop the front of your Nova 3 to 4 inches depending on tire size and spring settings. On top of that, the adjustable coilovers allow fine-tuning of the ride height so you can nail that killer stance. More than just looking cool, your slammed Chevy II will also have a lower center of gravity for even more corner-carving capability. 

We know from firsthand experience how G-Comp can totally transform the character of an old muscle car. G-Comp suspensions were not just designed to work on paper. They have been extensively driven, raced, and abused in our own fleet of test cars by Team Speedway, who can be found most weekends at the autocross track, dodging cones and taking notes about how to make G-Comp suspensions better, stronger, and faster.

Fully Bolt-In for Easy Installation with No Welding

Lucky for all of us, GM made it easy to remove the stock Chevy Nova front suspension. In fact, the whole front clip unbolts from the firewall, making it easy to ditch that archaic stock front suspension without getting out the torch or cutoff wheel. The G-Comp front subframe bolts right up to the stock mounting locations. Support tubes triangulate the assembly for added stiffness, and multiple mounting holes allow the supports to work on both ’62-’65 and ’66-’67 models. 

G-Comp suspensions are built in our state-of-the-art Lincoln, Nebraska manufacturing facility. Subframes and control arms are welded in precision fixtures and billet components are CNC machined to exacting tolerances. Every kit is then verified to ensure it will fit your car and deliver on the promise of true bolt-in performance. They ship to you in bare steel, ready for paint or powdercoat in your desired color scheme.

Rack-and-Pinion Steering Out of the Box

Rack-and-pinion steering is engineered into the G-Comp front suspension and the rack is included in the kit. A steering rack is lightweight, compact, and precise, offering quick and crisp steering feedback well suited to performance driving. That’s why the OE’s have been using them for decades. Because of all the benefits, installing a steering rack is a common upgrade to classic muscle cars, but care must be taken when installing a rack to the stock suspension. If the steering rack is not sized and positioned properly to work in concert with the suspension geometry, any improvement will be lost to nasty bump steer and dangerous handling. G-Comp suspensions are engineered with the rack-and-pinion where it needs to be to deliver safe, reliable, precise steering. 

Coilover and Brake Kits to Further Personalize Your G-Comp Suspension

Coilover shocks are a common upgrade for many classic muscle car owners looking for better performance. G-Comp suspensions are designed for coilovers, adding another dimension of adjustability and performance to the equation. Coilovers make it easy to adjust ride height and even change spring rates to tune the ride to your preference. We offer a variety of coilover shocks with fixed or adjustable valving. Adjustable shocks add yet another tuning option to dial in the perfect setup for your car. We have found with our fleet of test cars that an adjustable shock is a must for a serious track or dual-purpose car. The ability to adjust the shock’s compression and rebound is a valuable tool when it comes to setting up a car to handle just the way you want.

Recommended Coilovers:

G-Comp front suspensions are designed for coilovers with a 12” mounted length and an 8” spring. Coilovers are not included with the G-Comp kit. Below are our recommendations:

• AFCO 1340CT Pro Touring Fixed Valve Coil-Over Shock, 4 Inch Stroke (non-adjustable) 
• AFCO 12 In. Single Adj Pro-Touring Coil-Over Shock for G-Comp Chevy II (single adjustable) *Modification of upper shock tower hole for adjuster knob clearance will be required upon installation.
• AFCO 28400-1CR 8 Inch Extreme Chrome Coil-Over Spring, 400 Rate *Other spring rates are available to fit your specific application.

Recommended Brakes:

Brakes are not included with G-Comp suspension, allowing you to further customize your install by picking the kit that’s right for your car. G-Comp spindles work with widely available brake kits designed for 1964-74 GM A/F/X body cars.

• Stock Spindle 1964-74 GM A/F/X-Body 11 In. Front Disc Brake Kit 
• FDLI Pro Series 11 In Front Disc Brake Kit, 64-74 GM  
• Wilwood 140-7675 FDLI 12.19 Inch Front Disc Brake Kit, 1964-74 GM  
• Wilwood 140-12271 FNSL6R Pro Series Front Disc Brake Kit, 1964-74 GM  

’62-‘67 Nova G-Comp subframes use a special narrow steering rack that will use a ¾”-36 u-joint. An aftermarket steering column and mount are recommended for these cars since the original steering column requires extensive modification to work. 

G-Comp subframes are designed to work with both small block Chevy and LS engines. 

• Subframes come standard with brackets that accept Chevy motor mounts. 
• LS engines use small block motor mounts and motor mount adapter plates. 
• Front-sump LS engines must be converted to a rear-sump LS oil pan to fit into a G-Comp subframe. 
• While it’s possible to mount a big block Chevy to a G-Comp subframe, it’s not recommended due to the extra size and weight.  

Small block Chevy full-length headers and LS full-length headers were custom designed to work with G-Comp subframes. 

Inner fender panels and ’62-’65 fender braces as well as ’66-’67 fender braces are available to finish out the install into your Chevy II. 

The track width of the ’62-’67 Nova G-Comp kit is 56.” Most brake kits add 3/16" to 1/4" for per side for a total track width of 56-3/8" to 56-1/2." G-Comp front suspensions will comfortably fit an 18”x9” wheel with a 255-wide front tire.
